Trump literally doesn't understand doing something charitable for someone else.
He literally let his own fanbois and fangirls risk hypothermia after rallies in the winter because of stiffing the bus companies that got them there. TWICE.
Nah, he could have pardoned them before he left office but as usual doesn't give a flying fuck about anyone except himself. These idiots don't realize they were simply tools used and then discarded.
However, I could foresee a scenario where another candidate runs hard on the "pardon all the J6 'political prisoners' platform" and get some traction. That said, they would only follow-through if it got them political points or some other personal gain.
If he won he'd pardon himself for sure, this guy though? Doubt it. But it's a bit of a moot point. Nothing turns out the majority like voting against this fuckstick.
